What is the molecular weight they determined for this compound ?
The freezing point of water, H2O, is 0.000 °C at 1 atmosphere. Kf(water) = -1.86 °C/m
In a laboratory experiment, students synthesized a new compound and found that when 13.30 grams of the compound were dissolved in 250.1 grams of water, the solution began to freeze at -1.593 °C. The compound was also found to be nonvolatile and a non-electrolyte.

1 Answer
Explanation:
The freezing point depression observed for a solution, is proportional to the molality of the solute in solution....and here we have the appropriate parameters...
..where
And so
